Notes:
1. The minimum Read Setup Delay must occur after all opcodes that return data. See the SPI or I
2. Floating point values 1000.0 and 0.001 used for timing.
3. Long integer values 100 and 100000 used for timing.
4. Floating point values 30.0 and 0.001 used for timing.
5. Strings 1.2, 1.23, 1.234, … 1.234567 used for timing.
6. The timing depends on the register value and format specified.
7. The timing depends on the user defined function specified.
8. Instruction only valid in Flash memory.
9. Approximately (20 + 15 * order of the polynomial) microseconds.
10. Floating point values 0.25 and 0.75 used for timing.
11. Busy state is held indefinitely until condition is met.
12. Busy state is held indefinitely until user continues execution from debugger.
13. After 9 consecutive FF bytes the chip is reset, otherwise it is a NOP.
14. Depends baud rate, number of characters and operation.
15. The FFT instruction can do up to 64 point FFTs on-chip. The calculation times for these are as follows:
16. Depends on the transfer speed of the microcontroller.
17. Depends on size of matrix and type of operation.
instruction timing diagrams for details.
If the data is on the microprocessor, then read/write data transfer times must be added. For larger FFTs,
the FFT instruction is a multi-stage calculation.
2 point: 43 usec
4 point: 175 usec
